Use these 2 boosts with heimdall on your team. Let the unblockable and unstoppable activate and kill the defender.

It's also a risky play against dot champs because you have only 2 seconds(4 if you use the boost that doubles buff duration) to deal the final blow before you die to dot. Symbiote supreme should also stagger the indestructible and unstoppable, making the strategy also not work
